Reduced-pitch TIA supports 56-GBd PAM4 operation

EDN Network - Fri, 03/10/2023 - 01:36

Semtech has announced production availability of its GN1814 quad-channel transimpedance amplifer (TIA) for use in 400G and 800G data centers. The 56-GBd PAM 4 amplifier boasts a reduced I/O channel pitch of 500 µm and is well-suited for very high-density, single-mode fiber applications. It also offers low input-referred noise, high gain, and output-swing level detection.

“The production availability of the FiberEdge GN1814 enables qualification testing of the latest optical transceiver technology in data centers by our customers and system vendors who demand exceptional quality and performance,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “The reduced pitch of the new FiberEdge GN1814, combined with all the latest features from Semtech’s FiberEdge PAM4 TIAs and rigorous quality methodologies, enables the rapid deployment of next generation 100G/lane OSFP and QSFP-DD optical transceivers.”

The GN1814 linear transimpedance amplifier is available as wire-bondable bare die. It is intended for 400GBASE-DR4, FR4, LR4, and 800GBASE-DR8 PAM4 optical transceivers; chip-on-board optical assemblies; and silicon photonics. Log in or register for mySemtech to access product documentation.

Devices ward off ESD in automotive networks

EDN Network - Fri, 03/10/2023 - 01:36

Six ESD protection devices from Nexperia safeguard the 24-V board net systems used in trucks and commercial vehicles. The PESD2CANFD36XX-Q series protects the bus lines of in-vehicle networks, such as LIN, CAN, CAN-F, FlexRay, and SENT, from damage caused by ESD and other transients.

As data rates increase and vehicles feature more electrification, the need for ESD protection is critical. The PESD2CANFD36XX-Q series provides a maximum reverse standoff voltage of 36 V and up to 22 kV of ESD protection. Further, a low clamping voltage of 48 V at 1 A ensures system-level robustness for in-vehicle networks.

Available in SOT-23 and SOT-323 (SC-70) packages, the protection devices offer a choice of three different low-capacitance classes: 4.3 pF, 6 pF, and 10 pF. Low capacitance helps ensure smooth communication between interfaces without impacting signal integrity.

Devices in the PESD2CANFD36XX-Q series can be purchased directly from Nexperia or through its worldwide distributor network. View datasheets and check distributor stock using the link to the product page below.

Vision processors bring AI to intelligent cameras

EDN Network - Fri, 03/10/2023 - 01:36

Hailo-15 AI-centric vision processors from chipmaker Hailo deliver video processing and analytics at the edge when integrated into intelligent cameras. Hailo-15 SoCs deliver up to 20 tera operations per second (TOPS) running on a neural network core, processing multiple advanced deep-learning models in parallel.

Cameras outfitted with Hailo-15 vision processors can be deployed in smart cities, factories, and retail locations. Transportation authorities using Hailo-15 empowered cameras are able to recognize everything from accidents and lost children to misplaced luggage.

All Hailo-15 video processors support multiple input streams at 4K resolution and combine CPU and DSP subsystems with a field-proven AI core. The family includes three variants to meet the varying processing needs and price points of smart camera makers and AI application providers. These variants include the Hailo-15H (20 TOPS), Hailo-15M (11 TOPS), and Hailo-15L (7 TOPS).

According to the manufacturer, Hailo-15 processors enable over 5X higher performance than currently available solutions in the market at a comparable price point. For example, the Hailo-15H is capable of running the YOLOv5M6 object detection model with high input resolution (1280×1280) at a real-time sensor rate or the classification model benchmark, ResNet-50, at 700 fps.

Hailo-15 vision processors are engineered to consume very little power, making them suitable for all types of IP cameras and enabling the design of fanless edge devices. The small power envelope means camera designers can develop lower-cost products by leaving out an active cooling component.

Active bridge driver replaces lossy diodes

EDN Network - Fri, 03/10/2023 - 01:36

Alpha & Omega’s AOZ7203AV active bridge driver controls two external N-channel MOSFETs to replace two low-side diodes in an AC/DC bridge rectifier. The self-powered dual-driver IC can help improve efficiency and reduce standby power consumption when used in AC/DC adapters and power supplies.

“Today’s power-hungry gaming laptops, game consoles, and high-performance desktops demand high efficiency from the AC-DC power supply. Using the AOZ7203AV with AOS’ low-ohmic high-voltage external MOSFETs significantly improves the efficiency of the power converter as the typical rectifier-diode forward-conduction losses are reduced by 50%. Efficiency can improve up to about 0.7% at 90 V (AC) mains voltage,” said Armin Hsu, power IC senior marketing manager at AOS.

The AOZ7203AV is the latest member of the 600-V AlphaZBL family of active bridge drivers. In addition to minimizing forward-conduction losses, the part features ultra-low operating current, integrated X-capacitor discharge (CB safety certified), and a wide operating temperature range of -40°C to +125°C. A break-before-make function prevents shoot-through current when driving the low-side high-voltage MOSFETs in an active bridge rectifier circuit.

Available now in production quantities, the AOZ7203AV in 8-pin SO packages costs $1.68 each in lots of 1000 units.

Infineon to acquire GaN Systems, strengthening its GaN portfolio and further reinforcing its global leadership in Power Systems

ELE Times - Thu, 03/09/2023 - 10:10

Infineon Technologies and GaN Systems Inc. announced that the companies have signed a definitive agreement under which Infineon will acquire GaN Systems for US$830 million. GaN Systems is a global technology leader in the development of GaN-based solutions for power conversion. The company is headquartered in Ottawa, Canada, and has more than 200 employees.

“GaN technology is paving the way for more energy-efficient and CO2-saving solutions that support decarbonization. Adoption in applications like mobile charging, data center power supplies, residential solar inverters, and onboard chargers for electric vehicles is at the tipping point, leading to a dynamic market growth,” said Jochen Hanebeck, CEO of Infineon. “The planned acquisition of GaN Systems will significantly accelerate our GaN roadmap, based on unmatched R&D resources, application understanding and customer project pipeline. Following our strategy, the combination will further strengthen Infineon’s leadership in Power Systems through mastery of all relevant power technologies, be it on silicon, silicon carbide or gallium nitride.”

Jim Witham, CEO of GaN Systems, said: “The GaN Systems team is excited about teaming up with Infineon to create highly differentiating customer offerings, based on bringing together complementary strengths. With our joint expertise in providing superior solutions, we will optimally leverage the potential of GaN. Combining GaN Systems’ foundry corridors with Infineon’s in-house manufacturing capacity enables maximum growth capability to serve the accelerating adoption of GaN in a wide range of our target markets. I am very proud of what GaN Systems has accomplished so far and cannot wait to help write the next chapter together with Infineon. As an integrated device manufacturer with a broad technology capability, Infineon enables us to unleash our full potential.”

As a wide bandgap material, GaN offers customer value by higher power density, higher efficiency, and size reductions, especially at higher switching frequencies. These properties enable energy savings and smaller form factors, making GaN suited for a wide range of applications. By 2027, market analysts expect the GaN revenue for power applications to grow by 56% CAGR to approx. US$2 billion (source: Yole, Compound Semiconductor Market Monitor-Module I Q4 2022). As such, GaN is becoming a key material for power semiconductors, alongside silicon and silicon-carbide, and coupled with new topologies, such as Hybrid Flyback and multi-level implementations. In February 2022, Infineon announced doubling down on wide bandgap by investing more than €2 billion in a new frontend fab in Kulim, Malaysia, strengthening its market position. The first wafers will leave the fab in the second half of 2024, adding to Infineon’s existing wide bandgap manufacturing capacities in Villach, Austria.

The planned acquisition of GaN Systems in an all-cash transaction will be funded from existing liquidity. The transaction is subject to customary closing conditions, including regulatory approvals.
